MC74VHC157 Datasheet | onsemi

Quad 2-Channel Multiplexer The MC74VHC157 is an advanced high- speed CMOS quad 2- channel multiplexer, fabricated with silicon gate CMOS technology. It achieves high- speed operation similar to equivalent Bipolar- Schottky TTL, while maintaining CMOS low- power dissipation. It consists of four 2- input digital multiplexers with mon select (S) and enable (E) inputs. When E is held High, selection of data is inhibited and all the outputs go Low. The select decoding determines whether the A or B inputs get routed to the corresponding Y outputs. The internal circuit is posed of three stages, including a buffer output which provides high noise immunity and stable output. The inputs...
